There are fears of serious environmental damage following a study which has found high levels of lead, mercury and cadmium in dolphins from South Australia's Spencer Gulf.
A University of Adelaide researcher analysed liver samples of 114 dolphin carcasses.
The research student, Nicole Butterfield, says research now needs to be done on the affect of pollution on the animals.
"To actually see if these high levels of different metals is the cause of their death or is affecting their health."
Neil McDonald from the South Australian Fishing Industry Council has backed the call.
"Historically man's dumped his issues and problems in the sea and expected they'll simply get washed away and we now know that doesn't happen."
He says the metals could be causing serious damage to the marine environment."
